Thanks!

 Hi All!
 
 I installed mod_sflow on Apache and try to collect HTTP metrics by Gmond.
 The problem is that I don’t see any HTTP metrics coming from Hsflow to
 Gmond, nor HTTP counters via Apache http://hostname/sflow 
  page.
 There is a list of counters, but they all have 0.
 Like this:
 
 unter method_option_count 0
 counter method_get_count 0
 counter method_head_count 0
 counter method_post_count 0
 counter method_put_count 0
 counter method_delete_count 0
 counter method_trace_count 0
 counter method_connect_count 0
 counter method_other_count 0
 counter status_1XX_count 0
 counter status_2XX_count 0
 counter status_3XX_count 0
 counter status_4XX_count 0
 counter status_5XX_count 0
 counter status_other_count 0
 string hostname xx
 gauge sampling_n 0
 
 At the same time http://hostname/server-status?auto 
  is working properly:
 
 Total Accesses: 15
 Total kBytes: 5
 
 Uptime: 149
 ReqPerSec: .100671
 BytesPerSec: 34.3624
 BytesPerReq: 341.333
 BusyWorkers: 1
 IdleWorkers: 7
 Scoreboard:
 
 Is there a way to troubleshoot this? I need Sflow metrics.
 
 Thanks!
 S.

Re: [Ganglia-general] no_group metrics issue

2015-04-23 Thread Sergey 
Actually, it was resolved by GMOND config change:

“allow_extra_data=yes”

Thanks!
Sergey
